Modify your Firewall

Many companies have no Internet access restrictions and can therefore immediately start using your pascom virtual phone system without needing to make any alterations to their Firewall.

However, should you choose to, you can specify which internet services your company network is permitted to access by opening the following ports and allowing the pascom virtual server access in order to ensure that your pascom phone system operates optimally:

pascom Services

Port Host Description
TCP 80/443 my.pascom.net Access to the pascom licence server + PUSH services
TCP 25 cloudmx1.pascom.net, cloudmx2.pascom.net Access to the pascom Mailserver
UDP 123 * Access to the preferred time server (NTP)
